Note that the 13th Warrior is somehow inspired by the Beowulf's legacy so both film kinda feels the same, albeit one is animated,
13th Warrior is actually based on Eaters of the Dead. A great book by Michael Crichton
Its a GREAT read, and would also be a good way to pump you up for Skyrim.
Edit: It is slightly related to Beowulf, but a lot more realistic. So dont exspect to story to be the same.
Thor (pretty decent if you havn't watched it yet.)
How to Train Your Dragon (lol, but....I did like it)
Outlander (Corny as hell....but still VIKINGS FIGHTING SPACE DRAGONS!)
Valhalla Rising (I havn't watched this one yet but people liked it)
